How to Change an Inner Barrel – When it comes to the world of airsoft upgrades, the world really is your oyster; with a plethora of different modifications, you can make to improve the performance of your beloved airsoft guns. Throughout the years we have been playing airsoft, we’ve seen a number of different projects, from simple changes through to complete rebuilds; with individuals keeping a small part here or there from the original build. In reality, it’s very easy to get carried away with upgrading near on every part within your airsoft gun in an effort to increase the performance levels you receive from it.
When it comes to working on an airsoft gun, the complexity of upgrades honestly varies depending on the part you’re replacing. A lot of the time, it comes down to being meticulous with your upgrade, ensuring you take each step slowly and do not get frustrated in the process, as talking from personal experience, it can be very easy to break a product if emotion takes over.
Over the coming months, we’ll be taking a look at a range of different upgrades, ranging from shimming your gears through to installing a MOSFET. However, this month we thought we’d keep it simple, allowing you to dip your toes into the world of modifications in a relatively risk-free manner by replacing your inner barrel.
While we have pointed out above that this is a relatively simple upgrade, we would always recommend going to an airsoft technician if you feel uncomfortable at any point through the process. Just Airsoft Guns are in no way responsible for any damage you may cause by following these instructions.
Why Change an Inner Barrel?
Before getting into how to change an inner barrel, we thought it might be wise to discuss why you would in the first place. The inner barrel itself is connected to the hop-up mechanism which feeds each BB from the magazine. The BB then passes through the inner barrel as it is released from your airsoft gun. In short, the inner barrel plays a part in its accuracy and range.
When searching for a new inner barrel, you’ll notice there are a wide range on the market. In our opinion, we would personally only make use of the following brands — EDGi, PDI, Prometheus, ORGA, Maple Leaf and Mad Bull.
How to Change an Inner Barrel
So you’ve decided you want to change your inner barrel in the quest to improve your airsoft weapons performance, but just how do you go about it? Thankfully it’s a fairly simple process!
Step 1 – Unload and Turn the Hop Off
First things first – make sure your airsoft weapon isn’t loaded. By this we mean there isn’t a magazine in the mag well and there isn’t a BB in the chamber. Once this is done, you need to turn the hop off. This will vary dependent on the rifle, however as a general rule of thumb you want to turn it clockwise until it will no longer turn.
Step 2 – Remove the Body Pins
To gain access to the barrel, you’re first going to need to remove the body pins. These are generally found on the lower receiver of an airsoft weapon. Once this is done, separate the upper receiver from the lower receiver.
Step 3 – Remove the Inner Barrel
With the receivers now split, you should be able to remove the inner barrel. Bare in mind that this will be attached to your hop-up unit, so make sure you remove both as a single unit.
Step 4 – Remove the Hop-Up
To remove the hop-up from the inner barrel, you’ll need to do a couple of things. First off, you’ll need to remove the ‘C-clip’. This clip is located on the bottom of the hop-up unit and ensures barrel retention within the hop-up. Once this is done, you then need to remove the hop-up spacer, which is generally a gold ring. From there, you can simply slide the barrel out of the hop-up; which will also remove the hop-up bucking. With the barrel removed, remove the bucking.
Step 5 – Apply Silicon and Replace Bucking
With the barrel removed, you’ll now want to unpackage your new barrel. Once this is done, apply a silicon oil lubricant to the area that the bucking will slide on too. You’ll notice that the bucking has a slight raise inside, ensure this lines up with the indent on the barrel when sliding it on. With this done, apply more silicon oil to the hop-up bucking.
Step 6 – Re-Install the Hop-Up
Now step 6 is essentially the reversal of step 4. First of all, you’re going to want to reinsert the barrel and bucking into the hop-up. Following this you replace the barrel spacer and the C-Clip.
Step 7 – Finishing Touches
Now it’s as simple as sliding the barrel back into the upper receiver, making sure the hop-up tube is facing downwards. Once this is done, re-couple the upper and lower receiver and re-install the body pins. If you’ve made it this far, you’ve finished the job!
